head to head
Driver 2: Back on the Streets asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Execution · Practiced Mastery
Car control under pursuit pressure plus memorising city routes mission by mission.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Driver 2: Back on the Streets leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Driver 2: Back on the Streets leans clearly harder on execution.
Driver 2: Back on the Streets
Wrestling the car physics through chase missions is the test
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Driver 2: Back on the Streets
Police AI follows fixed pursuit logic, not adaptation
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Driver 2: Back on the Streets
Traffic placement adds run-to-run noise in chases
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Driver 2: Back on the Streets
Learning city layouts and mission routes carries completion
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
